Charl Schwartzel is on a run of six top-25s (including two at the majors) going into the week of the PGA Championship.

The world number 21 will bid for the Wanamaker Trophy from Thursday at Baltusrol Golf Club, where his prowess with long irons will be essential.

Schwartzel changed to PXG equipment during the week of The Open Championship and still managed a tied-18th result. He’s won three tournaments, each on a separate continent, in the last seven months.

He had to adjust his game for links golf at Royal Troon, but was pleased with his form.

‘It’s going to take a week to go build the swing back up. You do get some bad habits out of a week like this in Scotland, but I’m sure it won’t take me too long. I’m looking forward to the PGA Championship,’ he said last Sunday.

There is no doubt about his ability to contend at the season’s final major, where the best in the world are lining up.

Schwartzel is ninth on the PGA Tour for scoring average (69,775) and within the top 10 for strokes gained in both tee-to-green and approach-to-green.

Basically, he is hitting it really well and that’s exactly what Baltusrol demands.

The 31-year-old has almost no boxes left to tick this season, bar winning a major, and heads to New Jersey with one final goal in mind.
